* Fix some AIFF compatibility issues. * Fix some AIFF compatibility issues.
* Add support for setting a callback on an `ma_engine` object that get's fired after it processes a chunk of audio. This allows applications to do things such as apply a post-processing effect or output the audio to a file. * Add support for setting a callback on an `ma_engine` object that get's fired after it processes a chunk of audio.
